United States Patent O 3,102,281 WRAPPER-ATTACHING MACHINE FOR SHOE MANUFACTURE `Walter Schimming, Staten Island, N.Y., assigner to Herman Schwabe, Inc., Brooklyn, N.Y., a corporation of New York FiledApr.` 18, 1962, Ser. No. 188,378

16 Claims. (Cl. 12-1) This invention relates to the manufacture of shoes, especially floater-type shoes, and more particularly to a wrapper-attaching machine for use in the manufacture of such shoes.

The present machine facilitates the m-anufacture of a casual shoe having a peripheralwrapper, sometimes called a iioater type shoe. Such la shoe has an upper made of leather or fabric; a` sole which is usually thick rubber, say one-half inch thick; and it additionally has a wider strip of rubber secured around the periphery and concealing the edges of the sole and the -bottom edge of the upper. The top edge of the strip is sewn to the upper, and the remainder is glued in position. Such -a strip is commonly called a Wrapper.

This Iloater shoe differs importantly from a so-called sneaker or athletic shoe in that :the latter is vulcanized at high temperature. The iloater shoe -is not subjected to high temperature, land there is no yulcanization. The

`wrapper is simply cemented in position.

The sole is applied 4to the shoe before the wrapper is cemented in position. One object of the present invention is to provide means toapply a. substantial inward radial pressure against the Wrapper towobtain a strong cemented bond. With this object in view I provide a plurality of horizontal hydraulic cylinders which exert the desired inward radial pressure. 'Ihis pressure tends to deform the rubber sole, thereby reducing the radial pressure, and spoiling the intended-relation of lthe parts of the shoe during the cementin-g operation. Equally or `even more important, the `deformation of the sole may spoil the previously established bond between the top surface of the sole and the bottom of the insole. Deformation of the shoe also may tear the wrapper at its sewed seam.

Accordingly, one primary object of the present invention is to eliminate deformation of the sole and shoe while subjecting them to substantial inward radial pressure in chine. Such ra machine provides twoy stations, so that lthe operator may cement and load one shoe into the machine while the preceding shoe is setting under pressure. The application of pressure to the next shoe may be automatically accompanied by the release of the preceding shoe, the operator then being free to remove the treated shoe and to prepare tand load another shoe in the ma- The present invention is also applicable to the machine of -Haas Patent 2,843,864 granted July 22, 1958, and entitled Shoe Sole Attaching Machine, in `which the release is timed by adjustable clock control, that is, the two stations lare relatively independent of one another.

The mechanism of the aforesaid patents affords a fast rise of a shoe pad carrying a |lasted shoe until it reaches the toe and heel stop posts. In accord-ance with another feature [and object of the present invention the radial pressure is delayed until after the shoe is cl-amped in position. f

To accomplish the foregoing general objects, and other 3,102,281 Patented Sept. 3, 1963 Z more specific objects which will hereinafter appear, my invention resides in the Wrapper-attaching machine elements and their relation one to anotherV as are hereinafter more particularly described in the following specification. The specification is accompanied by drawings in which:

FIG. l is a perspective view showing a machine embodying features of my invention;

FIG. 2 is a plan view, drawn to larger scale, showing one of the shoe pads with fou-r horizontal cylinders for exerting radial pressure on `the wrapper of Ia lasted shoe, the top plate of the shoe pad being removed to better show the movable parts;

FlG. 3 is a vertical section taken approximately on the plane of the line 3 3 of FIG. 2, with the top plate restored;

FIG. 4 is a `fragmentary vertical section through a lasted shoe with its stitched wrapper, before cementing the same;

PIG. 5 is a flow `diagram for the machine shown in FIG. l; and

FIG. 6 is a -flow Idiagram for a diffe-rent machine embodying the present improvement.

Referring to the drawing, and more particularly to FIG. 4, the shoe comprises an rupper 12 which is sewed` at its lower edge to an insole 14. The same stitching, or more usually another line of stitching, is employed to stitch a wrapper 16 to the upper 12. Ordinarily one line of stitching will go through two of the parts, while the second line of stitching will go through all three. The wrapper 16 at this time is la band or strip lyingabovethe stitching, as shown in broken lines lat i16, but it later is turned down, as shown in solid lines at 16, so that it will lie around the periphery of the outsole 18. A filter, for example cork, is disposed between the insole 14 and the outsole 18, as shown at 2li. The soles and ller are preliminarily secured together, as by cementing, or in any other suitable fashion. The construction of the shoe may vary, and is not important in Ithe present invention,

down about the sole and is pressed to adhere the parts together. Dru-ring this operation the shoe preferably is iilled by a last 22. Eventually any excess width of wrapper is trimmed flush with the bottom of the sole.

Machines have already been proposed to lfacilitate this cementing operation by applying force against the wrapper to improve the lcemented bond. However, these machines have not proved wholly satisfactory. I have found that the pressure heretofore exerted was quite limite-d compared to optimum pressure for producing a strong bond. I have found further Vthat it will not do to simply increase the pressure, because this leads to deformation of the sole portion of the shoe.

Referring now to FIG. l, the side pressure here is exented while the lasted shoe is in a press generally resem- (bling a sole laying machine, thereby exerting a substantial vertical pressure on the sole of the shoe to prevent deformation of the same. The machine comprises a frame 24, 26 and 28 carrying Va pad box generally designated 30, and a main upright cylinder and piston, in this case located beneath the pad box, for compressing the bottom of a lasted shoe.

Referring now to FIG. 3, the pad box has a bottom 32.,` and two side walls 34. FIG. 2 shows the two end Walls 36. There are horizontal cylinders 38 mounted on the outside of thel side walls 34, and horizontal cylinders 40 mounted on lthe outside otf .the end walls 36.

End pieces 42 within the end walls 36 are'adapted to E be moved inward by the end cylinders 48. There are also side pieces 44 which are inside the side walls 34 and adapted to be moved inwardly by the side cylinders 38. The side pieces 44 are preferably considerably shorter than the space between `the end pieces, in order to provide clearance for inward movement of the end pieces and of the side pieces.

There are yieldable pads 46 and 48 inside the side pieces `44, and yieldable pads 58 and 52 inside the end pieces 42. These are shaped to conform to the shape of the shoe which is to be wrapped. Additional yieldable rubber llers 54 may be shaped and dimensioned for insertion between the end pieces 52 and the shoe, to adjust the box for a smaller size of shoe.

The cylinders 38 and 48 are prefer-ably single-acting cylinders, and to restore the same to outward or open position they vare provided with restoring springs. These may be internal or external. In the present case the end cylinders 40 have internal springs. A compression spring 56 is disposed around piston rod 58 between piston 68 and the end 62 of the cylinder.

The cylinders 38 have no internal restoring springs. Instead each side piece 44 has two outwardly projecting threaded rods 64, and there are compression springs 66 disposed between the side wall 34 of the pad box and an adjustable nut 68. If this nut is turned inward on its threaded rod 64, the force of spring 66 is increased. The adjustment may be locked by use of a lock nut, as shown. If no adjustment is wanted the rods 64 may be smooth rods.

Referring to FIG. 3, a thick yieldable pad 70 is disposed on the bottom 32 of the pad box. The inwardly movable pieces 44 are located just above the pad 70. These pieces preferably have an L cross section, and may be made of short lengths of angle iron. This helps support the pads 46 which are moved inward thereby. Similar remark applies to the end pieces 42. A cover plate 72 is preferably screwed in position over the top of fthe pad box. rPhe opening through the cover plate is large enough to receive a shoe of large size. The cover plate has Ibeen removed in FIG. 2 in order to better show the subjacent parts. If desired, several cover plates may be provided, with openings of different size, to take care of extreme variation in shoe size. The cover plate helps restrain and guide the side pads when in use.

Reverting now to FIG. 1 of the drawing, the machine in preferred form has two stations. The base 24 of the machine `acts also as a fluid reservoir and includes a submerged electrically driven pump to supply pressure lluid. There is preferably a spring pressed accumulator to speed the initial movement of the upright cylinders, as is described later. The operation of the stations is controlled by foot treadles 74 and 76, so arranged that one station is released when the other is clamped. The treadles may be a pivoted lever.

In the form here shown the frame of the machine includes a single post 26 extending upward from the base, and a -crosshead 28 secured rigidly across the upper end of the post 26. The ends of the crosshead carry horizontal bars 78, and these have depending adjustable ltoe posts `Si), and heel posts 82, which are disposed over the shoe pads -30 for bearing against and arresting upward movement of a lasted shoe in the shoe pad.

In FIG. 1 it will be seen that there are ilexible pipes 84 which connect the four horizontal cylinders together, and thence to a regulating valve 86. This leads downward to the upright cylinder or/ and to the source of pressure fiuid, but because the ilow to the horizontal cylinders is intentionally constricted relative to :the ow to the upright cylinder, `a shoe -in the machine is put under vertical pressure before horizontal pressure is applied. This is important and highly preferred because it prevents even momentary deformation of the sole, such as would occur if the horizontal force were to be applied preceding the vertical force.

The delay in the operation of the horizontal cylinders may be obtained by separate valving combined with a special delay means. However, a simpler way to obtain delay is by using a relative constriction of the llow to the horizontal cylinders. This may be adjusted at needle valves `86, one for each station. In FIG. l both are shown at the right, but in practice the valve for the left station is at the left, the machine being symmetrical.

The present improvement may be applied to a press which is not clock operated, such as the press in the above mentioned Haas Patent 2,783,486, or to a press which is clock operated, as in the above mentioned Haas Patent 2,843,864. The essential difference is that in the first press one station is released when the `other is clamped, and vice-versa, whereas in the second press each station is clamped independently by touching a separate treadle, and the release depends on the timing set in advance on a clock.

The press -illustrated in FIG. 1 is of the rst type, and its control mechanism is schematically shown in FIG. 5. The pump 102 supplies iiuid under pressure to a valve 104, which is of the sliding piston type. The valve is moved by a valve rod 186 under control of the tiltable treadle previously mentioned. When moved to the left, pressure iluid is supplied to the left hand cylinder 90, while the right hand cylinder 96 discharges through pipe 108 to the reservoir or tank 118. At the same time pressure lluid flows through pipe 88, adjustable needle valve 86, and the four hoses 84, to the four horizontal cylinders, not shown. When the valve is moved to the right hand position, the right hand station is activated, and the left hand station is released. In midposition the supply from the pump preferably but not necessarily is blocked, thus keeping the spring-pressed accumulator 112 under pressure while both stations are released.

Excess fluid returns to the tank from a relief valve 114 which determines the maximum pressure permitted in the system. The accumulator also is loaded during the clamping of either station because after the pistons have moved the accumulator builds up its reserve, and the cylinder pressure builds up. When the valve is shifted to apply pressure to the other station, the accumulator piston is immediately moved by its spring, and helps move the vertical cylinder piston rapidly to clamping position. Thereafter, as the pump continues operating, the accumulator is restored to loaded condition and the pressure in the cylinder builds up.

'The pressure gage at the top lof FIG. 1 shows the pressure, and helps properly adjust the relief valve (114 in FIG. 5).

The operation of the clock-timed machine may |be explained with reference to the low diagram shown in FIG. 6. This corresponds generally to the flow diagram in FIG. 5 of the aforesaid Patent 2,843,864. One main change is in the addition of the horizontal cylinders 38 and 40 with their flexible hoses 84 leading to regulating valves 86 and pipes 88. These are connected to the lower ends of the main cylinders 90, so that the horizontal cylinders are actuated with the vertical cylinders, except for the effect of the intentionally constricted ow to the horizontal cylinders. -i

A pump is shown at 160, immersed in a tank of lluid as indicated at 162, and driven by an electric motor 174. The inlet is taken through a sieve i164, and is delivered to a spring accumulator 166, which also may be immersed in the fluid. The pump output is connected through pipe 168 to a pressure relief valve 170, having a control handle 144 located for ready adjustment. Overflow from the relief valve is returned through pipe 172.

The pressure fluid is connected through pipe 176 to a rst Valve i178 for cylinder 180 at one station, and to cylinder 182 for the other station through a pipe 184 and valve 186. These valves are preferably solenoid actuated, as is indicated by the solnoids 188 and 190. In one posi- The check valve 194 prevents any lessening of pressure inV clamp cylinder 180 when pressure is iirst applied to clamp cylinder 182, and conversely the check valve 195 of clamp cylinder 182` prevents lessening of pressure in the latter `when clamp cylinder 180 is first actuated.

` Becauseof the check valves it is not possible to drain the cylinders through :the"B ports, and it is for this reason that separate A ports are'prov-ided, with connections `which-bypass the check valves.

Theitreadles 244 and 246 are connected to their respective timing clocksv 250`and 252', and the latter are connected `to` the solenoids 188 and 190 of theY solenoid "valve 178 and 186. When the valves are closed the spring accumulator 166 is charged. When a valve is opened there is a rapid supply of iluid at low pressure from the accumulator. This is adequate to quickly move the pads and shoe to desired position. The pressure then restores the accumulator and builds up to the maximum or squeeze pressure.

`The pipe connection to the vertical cylinder is short` and direct. VThe pipe connections to the horizontal cylinders are longer and more constricted. Also four hoses lead from a single pipe. The response of the horizontal cylinders is therefore slower than that of the vertical cylinders, which is lasit should be, so that the sole is clamped and held before horizontal pressure is applied. This result'is yfurther assured lby the use of the needle valve 86,vwhich is` adjusted to constrict and delay the flow `as much as may be necessary.

p As a specific example, the upright cylinders may be given `akdiafrneter of three inches; the horizontal side cylinders a'diameter of one and one-half inches; and the horizontal end cylinders a diameter of one inch.

Atypical working pressure for the hydraulicsystem is three hundred -fty pounds per square inch. The' rubber pad"`f70 `beneath the shoe. may have a hardness of sixty durmeters and a thickness of one and one-half inches. The side pads have a height of, say one inch. As will be seen in FIGS. l2 and 3, the side pads are built up of two types of rubber. The outer pads, that is the side pads 46 and the end pads 50, may` have a hardness of say seventy durometers, while the inner pads, that is'gwthe side pads 48 and the end pads 52 (and iiller pads 54,` when used) may have a hardness of say fifty durometera and are preferably made of good natural gum rubber. The tiller pads 54 have gradually tapering sides V,which overlap theside pads 48, and which provideja Ydesired.continuity around the periphery of the shoe.`

It'will'` be understood that the foregoing dimensions anni` valu-es` are given solely by way of example, and are not intended to be in limitation of the invention.

It is believed that, the construction and operation of my improved wrapper-attaching machine, as |well as the advantages thereonjwill be apparent from the foregoing detailed description.

eral preferred forms, changes may be made in the struc- `tures showm, without departing 'from the scope of` the invention as sought tobe defined in the following claims.

Inthe claims the reference to the use of rubber pads vis not `intended to exclude other resiliently yieldable materials having Ithe properties of rubber. The referenceto hydraulic cylinders is not intended to exclude the use of air .instead of oil or water as a iluid medium. The reference inthe claims to the horizontal cylinders being on the outside of the side walls or end walls is It will also be apparent that l while l have shown and described my invention in sevnot intended to exclude a cylinder mounting a part of which happens to pass partly or wholly through the wall.
